Question

Subtract.

(x2+3x−7)−(3x2−5x+3)



Express the answer in standard form.

Enter your answer in the box.

Answer 1

`-2x^2+8x-10`

Explanation:

Like terms are those which have same variable to the same power.

Standard form of any quadratic equation is in the form of:

`y=Ax^2+Bx+C`

To subtract :

`(x^2+3x-7)-(3x^2-5x+3)`

Remove the parenthesis;

`x^2+3x-7-3x^2+5x-3`

Combine like terms;

`-2x^2+8x-10`

Therefore, the answer in standard form is,
`-2x^2+8x-10`

Answer 2

(x^2+3x−7)−(3x^2−5x+3)

x^2-3x^2 +3x -(-5x) -7-3

x^2(1-3) +x(3+5) -(7+3)

-2x^2+ 8x-10
